The bearings of the cooling fan are mostly composed of oil bearing and ball bearing. During the initial use, the oil bearing produces very little noise, but is prone to wear and tear, and its service life is much shorter than that of ball bearing. Why is the lifespan of oil bearing type heat dissipation fans not long? Follow the editor to learn more!
The lubricating oil of a heat dissipation fan that operates in a high-temperature environment for a long time will be dried. After the oil in the oil-containing heat dissipation fan dries, there will be direct friction between the bearing and the shaft core, producing a lot of noise, and finally stopping operation.
Usually, cooling fans are used in dusty environments. After a period of use, dust will be sucked into the bearing bore, accumulating more and more dust, leading to the cooling fan becoming stuck and stopping operation.
